Did you ever wonder what happened to Zach Stevens on "The O.C." after he skipped his prom to go have dinner with George Lucas... and was never heard from again? We've got some theories, starting with George Lucas kidnapped him, and ending with George Lucas ate him.

While Zach remains M.I.A., the actor behind the character,
Michael Cassidy, went on to star in The CW's "Hidden Palms" and "Privileged" -- and can be seen this season on
"Are You There Vodka, It's Me Chelsea," the Chelsea Handler helmed comedy on NBC, as reported by
our friends at TVLine.

Cassidy will star as Chelsea's (Laura Prepon) love interest, a totally handsome Harvard grad whose one flaw -- according to Chelsea -- lies in his very, very red hair. You don't get more ginger than this, kids.

The role was played in the original pilot by Jake McDorman -- but don't worry, "Greek" fans, McDorman isn't going far. He's been upped to a series regular on the show in a different role, that does not require a huge red wig.

If we weren't already planning to watch "Are You There Vodka," we certainly are now. Cassidy has a smile to die for, okay? And we're shallow. (We think Chelsea would approve.)
